Abstract
A glass-fiber product having a textured surface thereon (and its process of manufacture) is disclosed wherein the textured surface is obtained by relieving the stress in pre-stressed polymeric chips that have been distributed throughout a polymeric layer superimposed on a glass-fiber sheet.
Claims2
A wear-resistant product having a textured surface comprising:
- (a) a flexible substrate impregnated with polyvinyl chloride;
- (b) a layer of a synthetic organic polymer or polyvinyl chloride superimposed on said substrate;
- and
- (c) a plurality of chips of polyvinyl chloride having a K-value of 53-73 distributed throughout and embedded within said organic polymer layer, said chips of polyvinyl chloride having a higher K-value than the polyvinyl chloride of said layer of synthetic organic polymer having been stressed prior to embedding and having been relaxed after embedding to provide a textured, wear-resistant surface of said chips and recesses between chips, said surface being characterized by a polymeric covering of substantially uniform thickness over both said chips and said recesses.
